5.7 H: Terminal Functions
Setting 58: Safe disable status
This terminal closes if either o f the Safe Disable inputs H1-HC or H2-HC are opened and opens when both terminals H1-
HC and H2-HC are closed.
Setting 60: Internal cooling fan alarm
This terminal changes states when the internal cooling fan fault is detected.
Setting 61: M otor pole search status
This terminal changes states when the Initial Motor Pole Position Search is finished.
Refer to Initial Rotor Pole Position
Search Settings on page 208
for details on Motor Pole Position Search.
Use this setting in applications where the motor speed feedback is supplied from a non-absolute encoder (e.g..
incremental) and where the drive brake sequence is not utilized.
Design the external brake sequence to interlock the brake as long as the Motor Pole Position Search has not finished. In
this case, the external brake sequence should be designed to interlock the brake during Motor Pole Position Search.

Search Error detection is enabled in parameter n8-86.
Setting 100 to 161: Functions 0 to 61 with Inverse Output
These settings have the same function as settings 0 to 61 but with inverse output. Set as 1ПП, where the “ 1” indicates
inverse output and the last two digits specify the setting number of the function.
Examples:
• For inverse output of “8: During baseblock”, set 108.
♦ H3: Multi-Function Analog Inputs
The drive is equipped with two multi-function analog input terminals: A1 and A2. Refer to
Table 5.13
for a listing of the
functions that can be set to these terminals.

0
Setting 0: 0 to 10 Vdc
The input level is 0 to 10 Vdc. The minimum input level is limited to 0%, so that a negative input signal due to gain and
bias settings will be read as 0%.
Setting 1: -1 0 to 10 Vdc
The input level is -10 to 10 Vdc. If the resulting voltage is negative after being adjusted by gain and bias settings, then
the motor will rotate in reverse.
■ H3-02: Terminal A1 Function Selection
Selects the input signal level for analog input A1. Refer to
Multi-Function Analog Input Terminal Settings on page 185
for instructions on how to adjust the signal level.
